The Application Binary Interface (ABI) defines how programs interact at the binary level. It is crucial for compatibility, function calling conventions, object layout, name mangling, and exception handling in C and C++.
Understanding the ABI is important for:
| In oreder to access Travis API, we need a client either via http , travis CLI (written in ruby), ruby(for making http headers) or travisPy(Python based travis API client). | |
| I used TravisPy as API client. https://travispy.readthedocs.io/en/stable/ | |
| Now, in order to extract errors thrown by travis servers we need to somehow access log files generated after each job. | |
| In order to extract logs, I followed the following route: | |
| User(1) ---> Repository(2) ---> Build(3) ---> Job(4) ---> log(5) ---> log.body()(6) | |
| 1) After installation of TravisPy by "pip install travispy", we need to authenticate user. |
